= Nielsen transformation
{wiki=Nielsen_transformation}
The Nielsen transformation is a mathematical procedure used primarily in the field of algebraic topology and related areas such as functional analysis. Specifically, it concerns the transformation of topological spaces and continuous mappings. One of the most common contexts in which the Nielsen transformation is discussed is in relation to Nielsen fixed point theory. This is a branch of mathematics that studies the number and properties of fixed points of continuous functions. The Nielsen transformation provides a way to systematically analyze and modify continuous maps while preserving their topological properties.
